No screen after i unpluged my phone from the charger there was no inside or outside screens but all other funtions work

Try charging the phone. The outside screen should indicate the charge level. If the outside screen is blank then the phone is likely to be faulty. If the outside screen works but the inside screen doesn't work, then the phone may be faulty.

It's the charger screwing with the phone. Unplug it and I bet it works fine. Find a new charger.

it's a good time to go get a new phone. that much damage would cost more in repair that it would to either replace or upgrade to a new phone.

change the flat of lcd if it dose not work change the lcd

yeah these phones do that alot the only thing that works is to pop the battery out and back in

If the inside screen and the outside screen is blank, the possible problem is the LCD flex cable. But if the outside sceen is on
but the large inside screen is blank. The large screen could be defective.

you will need to replace the LCD on the phone.

have the lcd replaced on both phones.

yes

the problem is with ribbon (flex cable).Take it to a qualify technician is not an easy lob
